Verdict
The clearest difference is review sentiment: Sticky at 63% against U Game Engine + xLua's 0%. Sticky also leads on price (Free vs $19.99) and ratings volume (8.8K vs 2). U Game Engine + xLua's advantage is rating (5.0 vs 4.5) and iOS requirement (15.6 vs 17.0). On update cadence, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Sticky is free to download; U Game Engine + xLua costs $19.99 up front. Sticky sells 16 in-app purchases, starting at $9.99 per 7 days and U Game Engine + xLua sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
U Game Engine + xLua holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sticky has 8.8K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of Sticky's written reviews are positive against 0% of U Game Engine + xLua's, so the app with the better star average is not the one people write more warmly about.
Sticky ships an update every 2 weeks, U Game Engine + xLua fortnightly. The most recent releases landed on October 11, 2026 and October 3, 2026 respectively.
